' .EIJEVATPB- Application filed September 1%;1920. SeriaI No. 411,931.

To all whom it may GORUTII-l Be it known that I, SANDER LANKHEET, a citizen of the United States, residing at Hamilton, in the county of Allegan and State of Micl1igan,'have invented new and useful.improvements in Elevators, of which the following is a specification. 1 i

'his invention relatesto an elevator and has for its primary object the construction of an elevator that will more effectively grip material or articles and will automatically release the same when reaching the delivery point.

An object of the invention is to provide a simple, light, portable, durable machine that may quickly elevate grain bundles on stacks or in barns.

Another object of the invention is to accomplish these forgoing results in a very eflicient, automatic manner.

A feature of the invention is the novel manner of constructing and associating the hooks with the chain and the movable frame so that the elevating action of the elevator may be changed without in any way interferring with the automatic opening and closing of the hooks.

With these and other objects in view the invention will be better understood from the following detailed description taken in connection with the accompanying drawing wherein:

Fig. 1 is a side elevation of the elevator.

Fig. 2 is a detailed plan view of a portion of the elevator.

Fig. 3 is an enlarged view showing the hook in loading position.

Figs. 4 and 5 are detailed views of the clip.

Figs. 6 and 7 are detailed views of the pivot construction.

Again referring to the drawing illustrating one of the many constructions of my invention the numeral 1 designates a frame mounted for swinging movement about the shaft 2 so that the upper end may be raised and lowered in the arc of a circle. The frame 1 includes a platform 3 ofa construction and extending in a direction to have fiat engagement with the upwardly traveling portion 4: of a chain 5. This chain 5 passes around an upper sprocket wheel 6 rotatably supported by the frame, and lower sprocket wheel 7 mounted on the shaft 2.

' The shaft 2 has a drive sprocket wheel 8 secured thereto which is engaged by the drive chain 9 driven in any suitable manner. A vertical stationary framelO supports the heretofore mentioned parts for their move ment. Arranged adjacent the lower end. of the frame, which is the (loading end, is a table 11 inclined so that the material or bundles arranged thereon will move towards the chain. Mounted upon the chain at spaced points are the hooks 12, each of a novel construction now to be described. Certain links" 13 of the chain have ears 14 provided with holes 15 for a purpose herein'after described The numeral 16 designates a sleeve bolted to the cars 14 of (near the links and receives the pin 17. The ears of the next adjacent link are bolted to the block 18 to which is secured a clip 19 that is provided with spaced holes 20. The nu-.

merals 21. and 22 designate the companion members of the hook. In this particular instance each member is constructed from a length of wire bent to provide a gripping limb 23, a supporting limb 24 and a. coiled portion 25 that is mounted on the pin for piv otal movement but held against displacement by the cotter pin 26. From this construction it will be seen that when the free end of the supporting limbs are passed through the holes 20 the companion members will be thrown about the pin 17 when the chain is making a turn so as to space the gripping limbs 23 at an inclination to the chain so that material or bundles will be efiiectively arranged uponthe hook at the loading end of the platform, gripped in its travel over the platform and mechanically released at the unloading upper end of the platform.

To complete the invention I provide an adjustable support 27 for holding the frame at any inclination necessary to deposit the bundles or material at the point of delivery. From the foregoing description taken in connection with the accompanying drawing it will be apparent that I provide an elevator of simple, inexpensive construction, and which, besides supporting the bundles or articles, will exert pressure thereon in the traveling of the bundle which is a great advantage when elevating bundles of strawv or grain.

It is, of course, to be understood that the invention may be constructed in various other manners and the parts associated. in different relations and therefore, I do not desire to be limited in any manner except as setforth in the claim hereunto appended.

Having thus described my invention what I claim is:

1. In an elevator construction, a traveling chain, rotary sprockets for moving said chain, hooks pivotally connected to the chain at spaced points, and clips secured to the chain at spaced points, said clips adapted to engage the adjacent hook during travel of the clips about the sprockets for moving the hooks into loading and unloading positions.

2. In an elevator construction, a traveling chain, rotary sprockets for moving said chain, hooks pivotally connected to the chain at spaced intervals, said hooks comprising gripping limbs and supporting limbs, clips secured to said chain at spaced intervals and engaging the supporting limbs of the hooks adjacent thereto whereby the gripping limbs of the hooks will be forced away from the chain into loading and unloading positions during travel of the clips about the sprockets.

8. In combination with a traveling chain,

a pivot pin secured to one of the links thereof, a. clip secured to another spaced link of the chain and provided with a pair of openings, and a pair of wire members, each hav ing a gripping limb, and a supporting limb having its free end mounted in one of the holes of the clip, said member being looped at the point of juncture of the gripping limb with, the supporting limb and mounted on said pin.

4. In an elevator construction, a traveling chain, rotary sprockets for moving said chain, pivot pins secured to certain of the links of said chain, clips carried by other oi the, links of said chain, and provided with a pair of openings, and article gripping hooks pivotally mounted upon said pivotpins, said clips provided with openings for receiving portions of said gripping hooks therethrough.

In testimony whereof I afiix my signature.

SANDER LANKHEET.
